Lab Brain for Claude Science

I built Lab Brain, a tool that turns any biomedical lab project — its code, slides, data, papers, and notes — into a shared knowledge base that both Claude Science and Claude Code can read and write. Everyone on a project works at the same time from their own Claude environment, and all of a project's knowledge ends up in one place instead of scattered across people's heads, chats, and folders. Most of the work went into creating the folder and file structures and skill/command frameworks that hold that together, which I iterated on from my own lab's practices. A START_HERE page always shows the latest updates linked to their files, clickable in Obsidian; some files get overwritten to the current state while others are append-only and keep growing, so nothing is lost. Handoff boards let people claim a file before editing so no one overwrites anyone else, and give mentees a scaffold plus a feedback loop with their mentors. Figures are named by content and logged in a registry, and old work is archived rather than deleted. Claude Science is a state-of-the-art harness, but it doesn't have a shared knowledge base — and research knowledge usually fragments across individuals working separate tasks. So I wanted to pull everything into one place that keeps growing, where people can build on each other's work, decide directions, and see what everyone's doing without losing context.
